1 Introduction

Aligns with the sustainable development needs of modern society and consumers' heightened awareness of energy-saving and environmentally friendly products, numerous countries and regions have implemented a series of policy measures, including financial support, preferential tax policies, and mandatory energy efficiency standards, to incentivize enterprises and individuals to adopt air conditioners with higher APF and SEER ratings.

As a leading semiconductor provider, Texas Instruments (TI) continues increasing attention to energy efficiency and environmental protection, leveraging advanced semiconductors to assist air conditioner manufacturers in enhancing energy efficiency standards at the system level.

Figure 1-1 illustrates a typical air conditioning system, including an indoor unit and an outdoor unit. The primary subsystems includes PFC, Auxiliary Power Supply, DSP, Compressor Motor Drive, Fan Motor Drive, Temperature and Humidity Sensors, as well as Millimeter-wave Radar. This document explores TI’s solutions for each of these subsystems.
